BRUSH.

Application filed July 14, 1928.

This invention relates to fountain brushes, and aims to provide a brush having a novel form of head to facilitate cleaning automobiles or the like.

The primary object of the invention is to provide means whereby the flow of water to the brush head may be readily controlled to the end that the brush may be used for cleaning, and by operatii'ig the valve, rinsing water may be applied to the surface under treatment to rinse the surface.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is z sectional view through a brush constructed in accordance with the invention.

Figure 2 is a sectional View taken on line f2-2 of Figure 1.

Referring to the drawing in detail, the device includes a handle portion indicated generally by the reference character 5, the handle nortion being in the form of a curved pipe having internal threads to :MKH)ll'lll'lOdtll'O the threaded extension 6 of the union 7 that also tits in to the supply pipe or hose with which the fountain brush is used.

Tl 1e body portion. is formed with a tapered bore to accommodate the valve 8, the tapered bore being shown as intersecting the passageway through which water passes to the brush head, to the end that by operating the valve 8, the supply of water to the brush head may be regulated at the will of the operator.

Positioned in one end of the tapered here is a plug 9 having an opening through which the valve stem 10 passes, the valve stem 10 being threaded at one of its ends and positioned. in a threaded opening of the valve 8, as clearly shown by Figure 1. Positioned on the valve stem 10 is a coiled spring 11 which is fitted between the plug 9 and the valve 8, so that when the valve is moved in one dirtc-v Serial No. 292,765.

tion, the spring will be compressed to return the valve to its seat, when the operating mechanism is released.

Ahead 12 is formed on the outer end of the valve stem and is engaged by the end 13 of the control lever 14 which is pivotally supported adjacent to the body portion to be engaged by the thumb of the hand of the operator to control the valve.

As shown, the body portion 5 is provided with a threaded extension 15 which [its into one end of the brush head 16 which is hollow and formed with a curved outer portion 17 substantially semi-spherical and provided with a plurality of openings 18 tl'irough which water may pass. Due to the shape of the por tion 17 it will be seen that water will be dirooted in all directions to engage the bristles.

The head also includes an outer flange 19 disposed in spaced relation with the portion 17, the length of the flange being such that the outer edge thereof extends to a point on a line with the outer edge of the portion 17, so that the bristles, which are indicated by the reference character 20, and which are positioned in openings formed adjacent to the base of the flange 19, are braced against the lateral pressure directed thereto by the force of the water passing through the openings of the curved portion 17 of the brush. H

From the foregoing it will be obvious that due to this construction an operator may hold the brush. with one hand and operate the valve to cause water to flow through the brush head illitibllSf-lGS while the brush being moved over the surface of a motor vehicle or article being washed.

It might be further stated that the bristles may be of the wire type so that the device may be readily used for cleaning stone, and while I have described the brush as adapted for use in cleaning with water, it is to be understood that steam may be forced through the brush and bristles for cleaning certain articles.

I claim:

A fountain brush including a body portion defining a handle, a hollow brush head removably secured to the body portion, said brush head including a semi-spherical apertured nozzle, a circular flange forming a part of the through the bristles. and means for controlling the passageol water through the body portion and head. In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
